Grille air outlets can enhance indoor air quality, reduce building energy consumption, and control local thermal and humidity environments in large spaces, gradually becoming a significant direction in the development of air conditioning in office buildings today. At the same time, they also pose new challenges to the design of traditional office building air conditioning systems. The layout of outlets requires comprehensive consideration of indoor air flow organization, noise, architectural aesthetics, installation and maintenance, as well as economic factors. When selecting, determine the outlet air velocity, calculate the air volume, effective area, and settings, and pay special attention to the impact of building beams or columns on air flow. For air conditioning areas with special technical requirements and high air volume, the selection of outlets should be supplemented by computer simulation (CFD) methods.
